My choice here to not write in depth the lack of tools to investigate profile issues.
I have a dell computer running Windows XP service pack 2 and there are three users currently on the machine. After about 10 minutes of being online (dialup service through AT&T) a Win32.exe error message appears and my browser then becomes "offline" even though I'm connected to my ISP it won't let me disconnect from it without shutting down my computer.
Do I have a virus and if so, why does it only affect me and not the other users of the same computer? How do I fix this?
